TIME-STAMP.

Specification of Letters Patent.

Patented April 20, 1909.

Application led October 24, 1904. Serial No. 229,868.

To all whom it may concern:

Beit kn own that l, GEORGE ELLioT PERRY, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented new' and nseful Improvements in Time-Stamps, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to time stamps, and has for one of its objects the provision of improved means for winding the motel1 mechanism of the stamp.

The other novel features of my invention will more fully appear from the following description thereof and from the accompanying drawings, in which l have illustrated one Way of embodying my invention in a practical device and in .vhich like reference characters are used to designate like parts in the several figures.

Figure 1 is a sectional vieiv of a stamp embodying my invention 5 Fig. 2 is a vi evtT taken on the line 2-2 of Fig. 1, looking in the direction of the arrows, showin@ a part broken away; and, Fig. 3 is a view of the face of the impression mechanism; and Fig. 4 is a detail perspective of the disconnecting lever.

Referring to the drawings by reference characters, an inverted Ueshaped frame 1 is provided, the ends of legs 2 of said frame constituting gage parts adapted to engage the surface to be stamped, said frame preferably having side Walls 3, 3, adapted to inclose the mechanism of the stamp. Longitudinal slots e, e, are formed in the frame 1, said slots being adapted to guide the impression mechanism when said mechanism is moved to make an impression. The impression mechanism is suitably mounted upon a supporting plate 5, the ends of said plate being secured to a yoke 6, said yoke carrying a handle 7. Mounted upon the frame 1 is a tube 8, said tube being adapted to telescope with the handle 7 against the power of the coiled spring 9, preferably disposed Within said tube, When the stamp is operated to make an impression, the spring 9 returning the parts of the stamp to their normal positions after an impression has been made. Any suitable inking pad 10 is provided for inking the operative face of the impression mechanism, said pad being adapted to be carried ont of the path of the impression mechanism as the same is moved into engagement With the article to be stamped. rlhe pad 10 preferably consists of tivo men bers, each member being pivoted to the frame 1 and being adapted to be carried out of the path of the impression mechanism by small rollers 21, 21, carrier upon the sin porting plate 5 and adapted to engage the edges of the members of the pad 1G, as shown in Eig. 1. Any desirable means for inking the face of the impression mechanism may be substituted in lien of the drop pad above described.

l prefer to use revoluble dies 11 and 12 for indicating the time, said dies carrying pointers or hands, adapted to indicate the time upon stationarily mounted dials 13 and 14, as shown in Eig. 8. The die 11 is adapted to indicate the minute and the die 12 is adapted to indicate the hour, a small revoluble die 15 being provided for indicating the forenoon and afternoon of the day. Any suitable mechanism adapted to be relatively moved to indicate time may be substituted in lieu of the dies and dials above described, Without departing from the spirit of my ii vention.

The die 11 is adapted to be continuously driven by a suitable horologic motor mechanism 16 from the arbor 1'?, upon which the revoluble die 11 is mounted. rlie arbor 17' carries a small gear Wheel 1S, said Wheel being adapted to move the revoluble dies 12 and 15 relative to the die 11, to have said dies at all times in proper position for printing the time. The arbors of the revoluble dies and the gearing 1Q preferably disposed betiveen the supporting plate 5 and a sub-plate 20. The day of the month, month and year not having to be changed often, the same is preferably not driven by the motor mechanism 16, but may be stationarily mounted, in any suitable manner, upon the plate 5, as shown in Eig. 3. Any additional. impression characters may be suitably mounted upon the plate 5, as shown in Eig. 3. Carried by one of the arbors of the revoluble dies is a disk 22, the upper sur'n said disk being beveled, as shown in E g 1, and being adapted to engage pins carried by the driving arbor of the horologic motor 16. rlie pins 23 are adapted to drive the disk W hen the impression mechanism is disconnected from the motor mechanism to make an impression, the motor will continue to run, the pins 23 being adapted to engage the beveled surfaces formed upon the disk Qlafter'an iinpression lias beenfmade,

and are adapted to rotate said dislr slightly to compensate for the movement of the motor mechanism while the impression mechanism has been disconnected therefrom in malring an impression and thus synchronize the impression mechanism with the motor mechanism. The motor mechanism is mounted between plates 24 and 25, said plates being secured to the table l by screws or bolts 25, 26, or in any suitable manner. One end of the main spring of the motor mechanism is secured to a pin 27, the other end thereof being secured to the inner surface of the barrel 28, within which said spring is inclosed. A gear wheel 29 is carried by the pin 27 a similar gear wheel 30 beinOp secured to the barrel 28. The exterior surface of the barrel 28 is preferably screw-threaded, as shown in Fig. l, a block 3l being adapted to travel said screw-threaded surface, a lug or projection 32 carried by said bloclr being adapted to be engaged by two downwardly extending arms 33, 33, carried by the gear wheel 29. The arms 33, 33, are adapted to rotate the block upon the barrel 28, and to guide said block as it travels the screwthreads formed upon the exterior of said barrel.

rThe motor mechanism may consist of any suitable construction adapted to be driven by the main spring M, and in the form shown, the small gear wheel 34 is adapted to mesh with the gear wheel 30 mounted upon the barrel 28. A large gear wheel 35 carried u on the pinion of the gear wheel 34 being acapted to mesh with a small pinion 36. A large gear wheel or pinion 37 mounted upon the arbor of the pinion 36, is adapted to mesh with a small pinion 38, the pinion 39 carried upon the arbor of the pinion 88 being adapted to mesh with the small pinion 40, upon the arbor of which one of the members of the usual escapement mechanism is mounted, the other member thereof or balance wheel 4l being mounted upon a suitable arbor 42, a hair spring 43 being adapted to coperate with the escapement mechanism of the motor in the usual manner. Any suitable motor mechanism may be adopted in lieu of that above described.

Centrally disposed within the handle 7, and suitably secured therein, in any suitable manner, against rotation, is a bushing 44, said bushing being shown as riveted to the end of the metal casing or shaft 45. A central aperture is formed in the bushing 44, adapted to be engaged by a shaft 46, said shaft having a spiral groove 47 formed therein, said groove being adapted to be engage/l. by a pin 48, mounted in the bushing 44, as shown in Fig. l. rhe shaft 46 is adapted to rest upon a spur 49, said spur being formed upon the surface of a suitable sup orting plate 50, said plate being secured to tlie plate 25, by screws or rivets 51. The

shaft 46 extends through the frame l and carries a pinion or gear wheel 52, said gear wheel being adapted to mesh with the gear wheel 54, carried by a plate 53, the gear wheel 54 meshing with the gear 'wheel 29 carried by the pin 27 to wiich one end of the main spring is secured. IThe plate 58 is preferably L-shaped and is loosely carried by the pivot or shaft 27, a small spring 55 being adapted to engage the plate 53 to hold the pinion 54 in engagement with the pinions 52 and 29. Preferably pivoted, slightly eccentrically of the axis of the shaft 27 which is preferably formed iitegrally with the lever or plate 53 on a stationarily supported eccentric E and adapted to move freely thereon, is a plate 55, said plate` having an L-shaped projection 57, said proiection being aoapted to overla a the periphery of the gear v-fheel 29 and eing disposed within the path of the block 8l, said bloclr traverses the screwethreaded surface of the barrel 28, as shown in Fig. l. Each of the plates 53 and 56 carries a small projection, to which projections are secured the ends of a spring 58. The spring 58 is of greater strength than the siring 55, the spring 55 being adapted tohord the gear wheel-54 in engagement with the gear wheels 52 and 2Q, when the spring 58 is dormant, the spring 58, when actuated, as hereinafter described, being adapted to carry the gear wheel 54 from engagement with said gear wheels against the power of the spring 55.

The operation of the invention above described is as follows: As the handle 7 is depressed, the pin 48 engaging the groove 47 formed in the shaft 46, will cause the gear wheel 52 carried upon the end of said saaft, to rotate. The gear 52 meshing the pinion 54, which in turn meshes with the pinion 29, will cause the pinion 2Q to be correspendingly rotated, said pinion 29 being mounted upon the shaft 27, to which one end of the main spring of the motor mechanism is secured. As the opposite end of the main spring is secured to the barrel 28, which in turn is secured to the pinion 30, which is adapted to mesh with the gearing of the motor mechanism, it will be seen that power is stored in the main spring and said partially wound at each operation of the stamp, or each time the pin traverses the spiral groove 47 formed in the shaft 45, thus rotating the pinion 52. pivoted on a stationary part of the frame (as 25) is provided to prevent the uni Yinding of the main-spring when the handle 7 rises, and any well-known form of driving-connection, as, for example, a toothed clutch, (not shown) may be used to prevent the backward rotation of the pinion 52 with the rod 46, during the upward movement of the handle. As the main-spring is wound, as above described, by successive operations of A pawl P, suitably llO pression for storing en@ n sion mechanism with. the motor, and means operated by the movement oi the im .nession mechanism in makin cn impression for storine` energy in sain motor.
